I recompiled the RailsLogVisualizer for AIR beta. I added drag&drop of log files to bypass an AIR bug on Leopard. File.browseForOpen doesn't trigger the Event.SELECT when the file is selected. I haven't yet tried this version of the application on older versions of OSX or on Windows. Let me know how it works. Also the feedback when loading large log files could be improved, as the application seems to freeze once the progress bar is complete. Just be a little patient as the AVM is working hard for you to compute all these number.

Then you can navigation through time and see how many request where processed and drill down in specific action and specific methods. For example, here we can quickly see that for October 99 people signed up, 869 did login, 22 forgot their password.
